Re: 2.4.20-pre2-ac2 pcmcia panic + OOPS

[Michael Dreher]

Hi,

finally I was able to catch the oops related to this problem.
(handcopied)

ksymoops 2.4.3 on i586 2.4.20-pre2-ac2.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20-pre2-ac2/ (default)
     -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Warning (compare_maps): ksyms_base symbol GPLONLY_idle_cpu not found in 
System.map.  Ignoring ksyms_base entry
